Hi,
Usually these error messages are caused during runtime - i.e., whenever a Console I/O function is used (printf, scanf, etc.). There are some reports showing this across the forum (two very relevant ones are here and here).
However, they are very uncommon to happen during a program load. In your case it is possible the issue at hand may be related to the emulation package software you are running (the component that connects CCS to the emulator). A few threads hint that this could possibly be the case (here and here).
In this case, I would either try to update the emulation pack (check this reference) or install a more modern version (v5.5) in a separate directory and try to use it only to debug the project (or migrate everything in steps). If you create a new workspace for the new version, you can still do code development with the older version and therefore prevent any disruption in your current environment.
Hope this helps,
Rafael
